OPA374

OPA373, OPA2373 OPA374 OPA2374, OPA4374 SBOS279D − SEPTEMBER 2003 − REVISED DECEMBER 2004 6.5MHz, 585µA, Rail-to-Rail I/O CMOS Operational Amplifier FEATURES D D D D D D D D LOW OFFSET: 5mV (max) LOW IB: 10pA (max) HIGH BANDWIDTH: 6.5MHz RAIL-TO-RAIL INPUT AND OUTPUT SINGLE SUPPLY: +2.3V to +5.5V SHUTDOWN: OPAx373 SPECIFIED UP TO +125°C MicroSIZE PACKAGES: SOT23-5, SOT23-6, and SOT23-8 DESCRIPTION The OPA373 and OPA374 families of operational amplifiers are low power and low cost with excellent bandwidth (6.5MHz) and slew rate (5V/µs). The input range extends 200mV beyond the rails and the output range is within 25mV of the rails. Their speed/power ratio and small size make them ideal for portable and battery-powered applications. The OPA373 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1µA. The OPA373 and OPA374 families of operational amplifiers are specified for single or dual power supplies of +2.7V to +5.5V, with operation from +2.3V to +5.5V. All models are specified for −40°C to +125°C.
